Hi All,
I have a MS2 V3.0 with a relay board which Im in the process of trying to get the car started. I have all the other sensors working great but have not had a tach signal.
Im starting by just getting the tach directly from the Negative on the coil (easiest way on my car) this meant I wasn't able to check the tach from the stim.
I have the D1 in place and the zener diode in D2 (Reversed).
I have uploaded the .s19 onto the board and ran the tachref.exe with a nil response.
Although i don't have an oscilliscope i have checked with a meter and there is variation with the voltage both the coil and at the relay board. I have a DIYAutoTune cable between this and the v3.0 some I have assumed the board is getting a signal.
Any ideas or help?
Steve

Re: No Tach Signal
In further research I have found U3 in the wrong way round!
I have now installed it correctly with no luck.
Will keep posted once new one arrives.
cheers

Re: No Tach Signal
Solder a jumper across the zener (D2) and your stim should work. Remove the jumper before connecting to ignition.

Re: No Tach Signal
Ive tried the jumper with no success.
I think having the U3 in wrong has buggered it.
Will have to wait for new one to arrive.

Re: No Tach Signal
Well Ive replaced my U3 and still do not have any signs of Tach.
I have treid bypassing the Zener for testing from the Stim. Its powered through mains so don't think I have a power overridding issue.
Any Ideas?

Re: No Tach Signal
Does the problem happen just on the car, or can you duplicate it on the Stim?
Re: No Tach Signal
I had the problem with the car and the Stim.
I am now trying to get it to work solely working on the Stim.
I have the JimSTIM and have checked that with the LEDs and it is outputting an RPM Signal.

Re: No Tach Signal
Could you post a copy of your MSQ? Could be something like an over-aggressive noise filter.
Re: No Tach Signal
This is the latest .msq that Im using.

Re: No Tach Signal
I see you have it set up for wheel decoding but have not set a missing tooth number. Exactly what sort of ignition are you using?
Re: No Tach Signal
At the moment I am only trying to run off the coil!
I have a 36-1 wheel to go on in the future but the engine has to come out for that.
Where/what should be changed?

Re: No Tach Signal
